2. 1. Water–fat separation in magnetic resonance imaging and its application in studies of brown adipose tissue

   Author : Jonathan Andersson; Joel Kullberg; Håkan Ahlström; Mark Lubberink; Kerstin Lagerstrand; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brown adipose tissue; magnetic resonance imaging; water–fat signal separation; graph-cut; positron emission tomography; 18F-fludeoxyglucose; infrared thermography; machine learning; artificial neural networks; deep learning; convolutional neural networks; Radiology; Radiologi;

   Abstract : Virtually all the magnetic resonance imaging (MRI) signal of a human originates from water and fat molecules. By utilizing the property chemical shift the signal can be separated, creating water- and fat-only images. READ MORE

   Abstract : In this thesis some research questions regarding durability and quality of roads has been investigated. The questions are analyzed from an image analysis point of view and aims to be a complement to existing methods for analyzing asphalt. READ MORE

5. 3. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

   Author : Keren Fu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

   Abstract : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. READ MORE

6. 4. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis

   Author : Peter Holdfeldt; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; atherosclerotic plaque; ultrasound; classification; dynamic programming; carotid artery; image analysis; edge detection; graph cuts;

   Abstract : Cardiovascular diseases, due to atherosclerosis, are among the most common causes of death in the industrialized world. Atherosclerotic plaque composition as well as arterial diameter and wall thickness can be used to predict the risk of cardiovascular disease. These risk factors can be assessed non-invasively by ultrasound. READ MORE

7. 5. Analysis of Medical Images : Registration, Segmentation and Classification

   Author : Matilda Landgren; Mathematical Imaging Group; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : A large number of medical examinations involve images in some way. Images can be used for diagnostics, follow-up studies and treatment planning. In this thesis mathematical methods have been developed and adapted in order to analyze medical images. READ MORE
